TSYS provides payment processing and related solutions to banks, merchants, and consumers. It works through three segments—Issuer Solutions, Merchant Solutions, and Consumer Solutions (Netspend)—to handle card and POS processing, mobile payments, and online gateways such as MultiPASS and Authorize.Net, with fraud management and analytics to support secure transactions. The company moves electronic payments between card networks, issuers, merchants, and consumers across in-person, online, and mobile channels. It differentiates itself with a large North American footprint (about 40% market share for third-party issuer processing), an integrated ecosystem built through acquisitions and a merger, and scale serving millions of merchants and hundreds of institutions worldwide. Its goal is to provide a complete, secure payments infrastructure that enables broad reach and omnichannel payment options for issuers, merchants, and consumers.

Global Payments Bets Big On $600M Synergy From Worldpay

A $22 billion acquisition is a tough act to follow. But TSYS-parent Global Payments is betting big on its $600 million synergy target as it pushes forward with the $22.7 billion acquisition of Worldpay, a move that is expected to shake up the competitive dynamics in merchant services and payments technology. The acquisition, announced in April and expected to close in the first half of 2026, will see Global Payments divest its Issuer Solutions business to FIS for $13.5 billion, sharpening its focus as a pure-play merchant solutions provider. The combined entity will serve more than 6 million customers in 175 countries, processing $3.7 trillion in annual payment volume and 94 billion transactions — a scale that positions the company among the world’s largest payment processors. Central to the strategic rationale is an ambitious plan to realize $600 million in annual run-rate cost synergies within three years of closing. According to Global Payments, roughly a third of these savings will come from consolidating technology infrastructure and eliminating duplicative vendor and software spend
